In the industry various types of steel flanges used for the assembly of pipes and tubes. In fact, flange gives easy access for cleaning, modification, and inspection in the industry as well as commercial. A flange is a metal product and a wide range available in the market relates to sizes, material, shape, and dimensions. On the other side, flanges are fitted to each other by nut and bolt, apart from this; these flanges are jointed with piping systems and tubes either by threading or welding. Moreover, these flanges are designed for specific pressure to bear.
In addition, these flanges can be used for closing the one end of the pipe which is known as a blind flange in the industry. Thus, these flanges acknowledge as an internal part which used to support mechanical parts in the industrial industry.
The material which is used to make these flanges
Flanges are made according to their application and these applications are specific that’s why a diverse variety of flanges available in the market. Most of the time, these flanges are readymade with standards and quality. The two most common material which is used to make these flanges are mild steel and stainless steel. Besides these, there are other common materials which are used to manufacture or fabricate the flanges is the following:
-
- Carbon Steel
- Alloy Steel
- Titanium
- Cast Iron
- Nickel Alloys
- Aluminum
- Stainless Or Duplex Steel
Above mentioned materials are the most common material that used for making the flanges. Meanwhile, all the manufacturers will manufacture the flange if there is any specific material requirement besides the material.
How to measure the flange sizes and dimensions
During a designing of the flanges, it is categorized in a few steps which are the following:
- Bore Size
- Pitch Circle Diameter
- Outer diameter
- Flange Thickness
- Hole Diameter
- Raised Face Diameter
The type of assembly of a flange to the pipe or tube
These are the few points that acknowledged by the design engineer while designing the flange. Besides these above mention key points, there are the other things which are considered during the design, according to the application and assembly which are included but not limited to:
- Weld Joint
- Threading
- Socket Weld
- Lap Joint
- Blind
Significantly, Not only these flanges have their standards related to their material selection, size, and shape but also manufacturers are producing custom sizes of flanges if any specific requirement given by the customer.
